Shipping Surcharge

Ground Shipping Items

Some RC Planet's products can only be transported under ORM-D (Other Regulated Materials for Domestic transport). Shipping under ORM-D means that the product will ship via FedEx Ground only, and cannot be shipped outside of the US. These products include:

  • Non-Water Based Paint and Paint Thinner
  • Petroleum-Based Oil
  • Aerosol Type Products
  • Traction Compounds
  • Tire and Body Cleaners
  • Epoxy / Accelerators / Debonder

The US Postal Service will not transport ORM-D items, and will not show up as a delivery option during checkout.


For All Shipments: Special labeling requirements are needed to safely transport any Lithium products. Certain large Lithium Batteries will always require HazMat handling and will only ship via Fedex. If you would like to know more about FedEx and the safety precautions taken when transporting Lithium Batteries, please refer to the FedEx guidelines.

International Shipments: Lithium Batteries are regulated as HAZMAT (Hazardous Material) products and can be dangerous if not packaged properly for transportation. In smaller quantities, Lithium Batteries can be shipped via DHL without applying a HAZMAT fee. If you'd like to ship more than 2 Lithium Batteries, a HAZMAT fee will be applied for transportation. Please note that DHL only allows transportation of HAZMAT / Dangerous Goods to specific countries, some of which have limited service areas.

The US Postal Service prohibits international mailing of Lithium Batteries, as well as electronic devices that contain Lithium Batteries. These new regulations also prohibit shipments to or from Army, Fleet, and Diplomatic Post Offices. Because of these regulations, no US Postal Service shipping options will be available during checkout.

Domestic Shipments: Both FedEx and the US Postal Service are available as shipping carriers for most Lithium Batteries and electronic devices containing Lithium Batteries. Please note that the US Postal Service has a limit of three batteries per shipment; you can refer to the Domestic Mail Manual for further information.


Fuel is classified as a "flammable" liquid. RC Planet can transport limited quantities of flammable liquid under ORM-D (Other Regulated Materials for Domestic transport). Shipping under ORM-D means that the product will ship via FedEx Ground only. For larger quantities of fuel (Example: case quantities), it must be transported under HAZMAT. Transporting as HAZMAT means that the amount of fuel is considered hazardous and will be subject to shipping by Ground services, including a HAZMAT fee for the special transportation. Fuel cannot ship outside of the US.

Please note that the US Postal Service does not transport Fuel and will not show up as a delivery option during checkout.

Rocket Motors

Rocket Motors, Rocket Igniters and Rockets are classified as “Toy Propellant Devices” and can only be transported through Surface Mail with the US Postal Service’s Parcel Post. FedEx does not transport Rocket Motors, Rocket Igniters and Rockets. Please note that FedEx will not show up as a delivery option during checkout.

International Shipping Restriction


Due to circumstances and regulations that are beyond RC Planet's control, batteries cannot ship outside of the US when using the United States Postal Service as the shipping provider. However, RC Planet can ship batteries internationally using DHL International, but the quantity cannot exceed a total of 2 batteries with a capacity of 5000mah maximum. Unfortunately we are currently unable to ship this item to APO/FPO addresses and apologize for the inconvenience.


Due to distributor restrictions, the following brands are not available for sale outside of the 50 United States: Losi, Team Losi Racing, Blade, ParkZone, ECX, Hobby Zone, E-Flite, Vaterra, Dynamite, Pro Boat, Spektrum, JR Radio, Orion, and Hangar 9.

The T-Rex 500E Pro features high stability, excellent gust resistance, superior control feel, and as the 500 is just the right size/price, it is the ultimate choice for enthusiasts.

  • Main rotor housing with integrated washout base for lower CG and aerodynamically efficient, improving 3D performance.
  • Unique carbon composite technology which effectively strengthen the weak areas and simplify electronics installation.
  • Servos can be mounted directly onto frame without mounting nuts.
  • Rear in-frame rudder servo mount design for centralize 3G for best 3D performance.
  • Equipped with MX series high efficiency brushless motor, with heatsink style casing and embedded fan to dramatically improve cooling and increase power output.
  • Unique fast release gyro and receiver mount design for fast removal and sturdy attachment.
  • Uses high precision slant tooth (helical) main gear, with higher load sustainability and lower noise output.
  • Brand new tail gear box with higher material quality and easy maintenance.
  • Newly designed dual bearinged tail blade grips for zero slop rudder control precision and ultimate tail locking performance.
  • Highly efficient shaft driven tail system which effectively reduce power loss found on belt driven system, and at the same time increase performance during flight.
  • Brand new 4mm carbon rudder control rod and metal rudder pitch bell crank to further improve the rudder locking effect and controllability.
  • New style battery mounting platform to strengthen frame as well as provide mount for electronic speed controller.
  • New style lower CG landing gear.
  • Newly styled aerodynamic canopy for the ultimate fit, making the helicopter stand out.

The main rotor housing with integrated washout base allows for lower CG and aerodynamic efficiency, improving 3D performance. Composite technology is used throughout the side frames which cleverly strengthen the weak areas, and eliminated servo mounting nuts to simplify maintenance at the same time. Removable gyro mounting platform and receiver mount are more rigid and ergonomically friendly. Rudder servo is mounted inside the frame for more central CG point to improve 3D performance, as well as minimize crash damage to the servo. Superior quality tail gear box, thicker stronger side plates around tail drive crown gear. Newly designed dual bearing tail blade grips for zero slop rudder control precision and ultimate tail locking performance. At the heart of the helicopter, the high efficiency Align MX series motor provides outstanding continuous power.
